Abstract

Ethnopharmacological relevance Ginsenoside Rg3 from Panax ginseng has reported to have multiple pharmacological activities including anti-diabetics, anti-inflammation and anti-cancer. However, the effect of ginsenoside Rg3 on myogenic differentiation and muscle atrophy is unknown.Aim to the study In this study, we investigated the myogenic effect and underlying molecular mechanisms of ginsenoside Rg3 on myotube atrophy induced by tumor necrosis factor-α (TNF-α).Materials and methods C2C12 myoblasts were induced to differentiate for one day followed by the treatment of TNF-α along with vehicle or ginsenoside Rg3 for additional 2 days and subjected to immunoblotting, immunocytochemistry, quantitative RT-PCR and biochemical analysis for mitochondrial function.Results Ginsenoside Rg3 promotes myogenic differentiation and multinucleated myotube formation through Akt activation in a dose-dependent manner, without any cytotoxicity. Ginsenoside Rg3 treatment restores myotube formation and increases myotube diameters under TNF-α-treated conditions. Ginsenoside Rg3 enhances Akt/mTOR (mammalian target of rapamycin) signaling that in turn stimulates muscle-specific gene expression such as myosin heavy chain (MHC) and Myogenin, and suppresses the expression of muscle-specific ubiquitin ligases. In addition, ginsenoside Rg3 in TNF-α-treated myotubes significantly inhibits the production of mitochondrial ROS and restores mitochondrial membrane potential (MMP) and ATP contents. Furthermore, ginsenoside Rg3 upregulates the activities and expression of peroxisome proliferator-activated receptor-γ coactivator-1α (PGC1α) and the mitochondrial biogenetic transcription factors, nuclear respiratory factor-1 (NRF1) and mitochondrial transcription factor A (Tfam) in TNF-α-induced myotube atrophy.Conclusions This study provides a mechanistic insight into the effect of ginsenoside Rg3 on myogenic differentiation and myotube atrophy, suggesting that ginsenoside Rg3 has a promising potential as a therapeutic or neutraceutical remedy to intervene muscle weakness and atrophy.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Ginsenoside Rg3 enhances myotube growth and suppresses the expression of MuRF1 and MAFbx in TNF-α-induced muscle atrophy of C2C12 myotubes via the activation of Akt/mTOR signaling pathway.

    “Like ginsenoside Rg1, ginsenoside Rg3 enhances myotube growth and suppresses the expression of MuRF1, MAFbx in TNF-α-induced muscle atrophy of C2C12 myotubes via the activation of Akt/mTOR signaling pathway.”
  • Ginsenoside Rg3 enhances mitochondrial functions and upregulates the expression of PGC1α, Nrf1, and Tfam, and thereby protects TNF-α-induced myotube atrophy in C2C12 cells.

    “Furthermore, ginsenoside Rg3 enhances mitochondrial functions and upregulates the expression of PGC1α, Nrf1, and Tfam, and thereby protects TNF-α-induced myotube atrophy in C2C12 cells [149].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
